The molecule could be
Molecular formula : C7H6Cl2
Double bond equivalent calculation
C + 1 - H/2 - X/2 = 4
Presence of a benzene group
There are two different types of hydrgen, thus the benzene is monosubstituted
the substituent on benzene would be -CHCl2
Mass spectrum confirms the existence of 2 chlorines on the same carbon
C- 13 NMR also suggests there are 5 different carbons
